ATLANTA, Ga. (CNN) — More search warrants released Monday morning may reveal new information about the death of 22-month-old Cooper Harris. The Cobb County Magistrate tells CNN as many as seven warrants could include more details about Justin Ross Harris, the boy’s father, who sits in a Georgia jail charged with his son’s murder.

Over the weekend, Georgia homicide detectives continue their work into the case. Leanna Harris, the baby’s mother is also part of the investigation according to police.

It was just July 3rd that the public learned bizarre details about the case, like the internet searches on the father’s work computer, that included a visit to a web page devoted to exploring a child-free lifestyle, as well as a search for how to survive in prison.

Detective Phil Stoddard of the Cobb County Police said at the hearing, “Evidence is showing us right now that he’s got this whole second life that he’s living with alternate personalities and alternate personas.”

Detective Stoddard also said that Harris sent lewd text messages while his son sat strapped in a car seat in the broiling Atlanta heat, “He was having up to six different conversations with different women. The most common term would be sexting.”

Police also testified that the couple had money problems and that they’d both conducted internet searches on child deaths in hot cars. The defense, including attorney H. Maddox Kilgore, objected to much of Thursday’s testimony and painted Ross as a loving father who made a mistake, “It’s not criminal negligence. It’s a horrible tragedy and an accident.”

In the courtroom Leanna Harris’ face stayed mostly stoic. Cobb County Police Detective Phil Stoddard detailed her reaction on the day her only child was found dead, “In front of several witnesses, all of sudden she states. ‘Ross must have left him in the car.’ And they’re like, ‘What?’ ‘There’s no other reason, Ross must have…no other explanation’ excuse me. ‘Ross must have left him in the car.’ And they tried to console her and they’re like, ‘No there’s a thousand reasons. He could have taken him to lunch or something. We don’t know yet.’ And she’s like, ‘No.'”

Investigators say their work is far from over. Family and friends of the couple say judgment should be reserved until all of the facts surface. Also on Friday, search warrants revealed to the public showed that after Cooper’s death, Justin Ross Harris spoke to family members about how to collect on two insurance policies totaling $27,000.
